Sodium polytungstate is a relatively new agent for the production of heavy liquids, which offers substantial advantages over zinc chloride or highly toxic halogen hydrocarbons in sinkfloat analyses. It dissolves very well in water and can be configured as a pHneutral solution. The maximum density of the solution is g/cm³ at 25°.

Sodium polytungstate (CAS ) Market Research Report 2019 presents comprehensive data on Sodium polytungstate markets globally and regionally (Europe, Asia, North America etc.) The report includes Sodium polytungstate description, covers its application areas and related patterns.
In our experience, SPT (sodium polytungstate) and LMT (lithium metatungstate) are not used by many mineral labs which need a heavy liquid with a density of g/mL or more, because their solutions at these densities are too viscous. Typically the viscosity of these liquids is greater than 25 cP, or more than 25 times the viscosity of water.

Sodium metatungstate is the inorganic compound with the formula Na 6 [H 2 W 12 O 40], sometimes written 3Na 2 WO 4 ·9WO 3 ·H 2 O. It also called as sodium polytungstate (SPT). This salt has been used in the manufacture of dense aqueous solutions. Sodium metatungstate exists as white solid.
The number of electrons in each of Sodium''s shells is [2, 8, 1] and its electron configuration is [Ne] 3s sodium atom has a radius of pm and a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silverywhite metallic appearance.

Do not mix sodium polytungstate solutions with LST Fastfloat because the two materials are not compatible: a mixture of the two will not reach high densities. LST Fastfloat is not compatible with alkaline chemicals or alkaline solids such as lime. Only deionised water should be used for diluting LST Fastfloat heavy liquid.
